Hi, I see that there is already a tab system in javascript (AJAX), I need to see current codes to be sure that everything what is mentioned fully possible. There are some bugs which are not mentioned in the project, I do not count them. And... jigoshop must support giving data on request, to be sure that you may display some variables like pricing (otherwise this may be the matter of writing request for database). As well cart plugin must be setup already to understand requests from forms.
